Utako Kurosu, Mayako Kutsukake, Shigeyuki Aoki, Chuan-Chan Wang, How-Jing Lee, and Takema Fukatsu (2008) Hitherto unknown fig-shaped galls of a cerataphidine aphid were found on Styrax suberifolius
in a mountainous region of Taiwan. The morphology of 1st-instar
nymphs deposited by alates that had emerged from the galls accorded
well with the morphology of 1st-instar nymphs of Cerataphis bambusifoliae on bamboo. The mitochondrial DNA sequences from the gall and bamboo aphids also supported the identity of the 2 generations. The gall-living aphids are therefore considered to be the primary host generation of C. bambusifoliae,
and a description of the alates, apterous adults, and the 1st-instar
nymphs is given. We also revealed that, like other
cerataphidines, C. bambusifoliae produces many 2nd-instar, sterile soldiers in their galls.
Key words: Cerataphidini, Hormaphidinae, Host alternation, Mitochondrial DNA, Soldier aphid.
